There's really nothing you can do, except accept that they will need time to come to terms with it. I have no idea how your parents will react, and maybe it'll go well. If you think it is safe to come out, it's best to do so honestly and directly and when you feel ready. It's better to be independent from them when you come out, so if the worst scenario happens you still have a place to live etc. It's ok to be afraid.
It always makes me sad when people say the "respect" lgbt, because that's really just something to say to make one look like a better person. The reality is they do not respect lgbt+ community at all. If they really respect LGBT+ ppl, they would be ok if the person were in their own family. Of course, people change, if they begin as intolerant it's very possible that they'll come to embrace it later because they love you.
Best of luck to you, whatever you choose to do, I hope you'll fare well.
